P&J Construction recently completed my dormer extension. I had not had any work from the company previously locating them online. Their quote was realistic and value for money. My considerations when using builders are; 1. That they're close to their quote 2. That they're punctual & polite 3. That they clean up 4. That they're security conscious 5. They complete the work to a high standard I can say that P&J completed all of the above. Alex provided me a quote for the work & time of when the work could start. They turned up nice & early throughout the build so we could discuss what work would be carried out that day before i went to work. Due to bad weather they also worked long into the evening, worked weekends or simply got wet. They continued to graft through wintery conditions & surpassed my expectations. They created more floor space than what the architect suggested. When removing the roof they identified poor work left by previous builders and righted all wrongs. They had cleaned up after themselves and on completion of work they cleaned all areas of where they had worked which was highly appreciated. They were very polite to my wife and children and they were professional throughout. They always locked up after themselves and made sure all windows were locked. Best of all, the work came in at exactly what they quoted. Overall I am extremely pleased with the finished product.

Extensions- 19 Nov 2022
Steve and his team turned up on schedule, worked hard, were friendly, and communicated well. It's fair to say our project turned out to be more complex than anyone first thought and there were unforeseen circumstances to contend with. Steve stuck with the project and its challenges at all times, he worked through any concerns and problems with us. At the end of the day the build was completed, within budget and only a few days over the original time estimate. We would use Steve and his team again.

Latest review:
Extensions- 8 Jan 2023
Bourne Transformations went bust during the project and walked off site, despite my best efforts to keep them going - paying more for labour and for extra materials - for a project which had already gone well above their initial quote - partly due to expansion/changes - but also due to the quote not including vital parts of the project which I had thought would be there. They did not really seem to care, leaving us with an unfinished extension, leaking roof and a huge amount of work and Bourne owing us and other trades a lot of money. Although when they put their mind to it, they can do decent work across trades at a decent speed, the quality of work and pride in work was not what I would expect. Frequent mistakes, not following plans, extremely untidy site with litter and debris everywhere (which our friends and family all told us was a very bad sign) - the list of issues goes on. We all know it has been a hard time to stick to budget and this was a big project, but I don't have sympathy here, Bourne's extremely poor project management and failure to be on site, unreliable team (frequently not turning up or labourers getting sacked) and lack of commitment to the job were the main problem. The job could have been finished to budget if properly executed. On top of all this, all you get is excuse after excuse and broken promises. So, beware of hiring this firm.

Latest review:
Single storey rear kitchen extension - really pleased with the new kitchen. Yuri and his men built the extension and did all of the ground work too and then fitted the kitchen for me. As my existing kitchen plus the new kitchen extension together, is a very unusual shape, the fitting of the new units and appliances would have stumped most builders or kitchen fitters and I know that it was a very difficult job but Yuri fitted everything really well and kept his sense of humour at the same time.
